False ceilings
When used in false ceilings, the equal height of the bearer bars and insert bars of full gratings allows the elements on the other side of the false ceiling to be concealed.
Several finishes available
- Untreated steel
- Galvanized steel
- Stainless steel
- Aluminium
- Powder-coated
Custom manufacture:
GEI can manufacture made-to-measure full gratings to meet your requirements (layout, size, etc.). Various heights and thicknesses of bearer bars are available on request.
Mesh
The mesh spacing is defined in accordance with the standards and loads that must be respected:
- BB thickness of 2, 3, 4 and 5 mm
- The BB spacing is typically a multiple of 11.
- The IB spacing is typically a multiple of 11.1
Bearer and cross bar
- Standard heights: 20-140 mm.
- Standard thickness
Dimensions
- Maximum length of bearer bars: 4000 mm.
- Maximum length of spacers: 2000 mm.
Surface Treatment
- Galvanized in accordance with EN ISO 1461 standards.
- Stainless steel V2A or V4A available.
- Aluminum available.
Finish
- Available with "flat" edge or without edges.
- Available with single or double notching on request.
- HALF-MOON or SAWTOOTH notching available.
Finished Product
Custom manufacture based on the dimensions given by the customer or on plans drawn up by our research department.
GEI press-locked grating is characterized by transverse, cross bars inserted under high pressure into pre-existing notches in the bearing bars. This grating is produced in “flat” or “T”-shaped sections, welded into place and then optionally undergoes hot-dip galvanizing in accordance with the applicable EN ISO 1461 standards. For situations with an increased risk of slipping, anti-slip grating can be produced, where the upper surface of the bearing bars and/or the transverse bars can be given anti-slip serrations. GEI press-locked grating is typically manufactured from EN 10025 standard S235JR steel, which ensures a consistent production quality. RAL-GZ 638 manufacturing tolerances applied.
